[Xen-devel] [PATCH OSSTEST v4 08/13] Osstest/Debian: Add "clk_ignore_unused" to default command line

[Ian Campbell <ian.campbell@xxxxxxxxxx>]

dom0 is not aware that some clocks are actually in use (e.g. by the
hypervisor), so this stops the kernel from messing with (specifically,
disabling) those clocks. It's harmless even when not needed.

Really there ought to be some interface to communicate this from Xen
to dom0, or some other mechanism to gate things. See
http://bugs.xenproject.org/xen/bug/45
